BOX-CLOSURE Specification of Letters Patent.

Patented Aug'. 13, 190'?.

Application filed June 5, i906. Serial No. 320,307.

To all whom it may concern:

Be it known that l, JOHN P. NIKONow, a subject of the Czar of Russia, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Box lClosures, of which the following is a specification.

This invention provides a box or case of novel formation particularly designed for inclosing an electric fuse, switch, plug or like part required to be protected.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and accompanying drawings. I

While the inventionmay be adapted to different forms and conditions by changes inthe structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure l is a perspective view of abox or case embodying the invention. Fig. 2 is a vertical central section of the box. Fig. 3 is a view similar to Fig. 2 of a modification showing the cover thrown open. Fig. 4 is a detail view in perspective showing more particularly the hinge connection between the box and cover.

Corresponding and like parts are referred to in the following description and indicated in all tli'e views of the drawings by the same reference characters.

The box or body of the case is indicated by the numeral l and is preferably of circular outline and is provided in a side with one or more openings 2 through which the electric wires pass, a bushing or like part reinforcing the opening and acting as an insulator between the box and the electric wire. vThe box may be either cast or stamped or pressed from sheet material such as metal, paper, Aor the like. `-The cover 3 is somewhat similar in formation to the body of the box or casing, its rim snugly embracing the rim or sides of the box. The cover may be cast or struck up from sheet material.

As securing means between the cover and box, va fastening 4 is provided, the same consisting of a bow having its end portions secured to the box in any substantial manner and passing through a bayonet slot 5 in the rim of the Cover. The fastening -4 may be of wire or consist of a metal strip and is'adapted tobe attached to the box in any firm and secure Way so as not to be readily disconnected therefrom. 'When the cover is in proper position, the upper member Aof the bow asteningfl occupies a position in the horizontal member of the bayonetl slot 5, the covering having been turned so that the fastening 4 is out of register with the vertical member of `said bayonet slot.v When so positioned, the cover cannot be, thrown open because of the extent of lap of the portions or sidesjof 'the box and cover.A To prevent tampering with the box, a lock 6 of the hasp type is provided and is adapted to pass through the fastening lland a correspondingvloop 7 fitted to the rim of the cover ad# jacent to the end of the slot 5 opposite to the vertical member of said slot. When it is required to open the boxto gain access, to the interior thereof for any purpose, the lock 6 is removed and the cover partly turned to bring the vertical member of the bayonet slot in register `with the fastening 4, after which said cover is moved outward until the upper lmember of the fastening 4 occupies a position at the lower end of the vertical member of the slot 5, when the cover may' 'be'thrown openopposite to the connection upon the 8 which is clamped between the' cover and theupper edge of the box. The opening in the box through which the wire passes is'provided with a packing gland 9 of ordinary construction whichmay be tightened to compress packing material about the wire and prevent moisture finding its way into the box through the opening admitting the Wire. It is also contemplated to employ additional securingmea-ns, the saine consisting of a bayonet slot l0 and a pin-l1, the latter being applied to the box and the bayonet Vslot l0 formed in the rim of the Acover and opening through the edgel thereof. The pin l1 preferably consists of a set screw which may be tightened to further secure the cover -when in position. 4

A box or case constructed substantially as set forth is adapted to receive a fu e, cut-out, switch or like device desired to be housed or protected, said boxer casing being prevented from accidental opening by reason of the peculiar formation of the securing means between the body of the box or case and cover, said means admitting of opening and shutting the cover by a pivotal or swinging movement and providing permanent connection to prevent accidental loss or misplacement of the cover.

When the cover 3 is in position uponlthe box and the upper member of the fastening 4 is at the inner 1. In combination, a box, a cover therefor having a rim encircling the box and provided with a closed bayonet slot, one arm of said slot extending in the circumferential length of the rim, and the other arm of said slot being at a righty angle to the circumference of the rim, and a fastening applied to the box and passed through the bayonet slot and serving to prevent separation of the cover from the box while admitting of said cover having a limited turningr movement to bring the fastening in register with the arm o1 the bayonet slot at a right angle to the circumference of the box to admit of outward movement of the cover and a swinging of the same so as to uncover the box.

In combination; a box, a cover therefor having a closed bayonet slot, one arm of said slot extending around the rim ot the cover and the other arm at a right angle to the circumference of said rim, a bow fastening secured to the box and havingl one member passed through said bayonet slot :ind forming a hinge connection between the cover and box, and copel'nting means between the'covcr and said bow fastening to secure the cover, substantiallyas set forth.

In combination, a box, a cover therefor having an encircling rim provided with a bayonet slot, a bow shaped fnstening secured to the box and'having a member passed.
